[The change and significance of coagulation activity in bleomycin-induced lung fibrosis in rats].

Objective: To investigate the role of coagulation activity of bronchoalveolar lavage fluid (BALF) in the pathogenesis of lung fibrosis.

Methods: Fourty-eight Sprague-Dawley rats were randomly divided into 2 groups, 24 rats in each group. In the bleomycin (BLM) group, the lung fibrosis model was made by tracheal instillation of bleomycin A(5) (BLMA(5), 5 mg/kg).
